This paper describes how body regimes are effectuated in the prevailing treatment strategy of physiotherapy. The process of self‐mastering in the context of sports‐related injuries is highlighted. Through a Foucauldian perspective on body regimes the aim is to shed light on the process of individualization and self‐mastery in rehabilitation. The treatment of illness in the physiotherapy clinic does not characterize the patient as sick, and exempt the patient from daily duties and expectations. The empirical data include 17 qualitative illness narratives (...) and several years of fieldwork observing patients with anterior cruciate ligament (ACL) injuries in a physiotherapy clinic. The study demonstrates how the expectation that the patients be active and self‐mastering permeates the total process of treatment. The individual responsibility for personal well‐being is a recurrent phenomenon in public health services in general, and specifically prominent in the rehabilitation of sports injuries. (shrink)
